Question 15
In MPLS QoS , traffic policies are developed on simple traffic classified and complex traffic classification
policies based on simple traffic classification the service class color, and drop priority of packet are reset based
on the packet in the traffic policies on complex traffic classification measures such as traffic classification is
applied on border routers in Different domain, and traffic classification core routers. QoS policies are
configured by performing the following operations:
* Defines DiffSer domain and configuring a traffic policy.
* Classification traffic
* Defines traffic behavior and configures characteristics ofbehaviors.
* Defines a traffic policy and specifies for trafficcategories
* Applies the traffic policy
* Configure L-LSP
* Configures reserve address checks
* Adds interface to the DiffSer domain
Which of theproceedingoperations are required when you configured simple traffic classification?
